Academic Achievement of ELs and Students With LD
Nationwide, ELs comprise 9.5% of the K-12 student body, with rates ranging from 1% in West Virginia to 21% in California; rates overall have increased since 2000 (U.S. Department of Education, 2018). In the U.S., most (77.1%) ELs have a home language of Spanish or Castilian, comprising over 3.5 million U.S. students. U.S. Department of Education statistics for 2015-16 indicate that 6.7 million students were eligible for special education in the U.S., about 14% of the K-12 population; across disability categories, learning disabilities were the most prevalent, with 34% of students in special education qualifying (U.S. Department of Education, 2018).
The National Assessment of Educational Progress (NAEP; National Center for Education Statistics [NCES], 2018a; 2018b) shows some recent improvement in science test scores for fourth-, eighth-, and 12th-grade Caucasian, African-American, and Hispanic students. However, achievement gaps remain, particularly with ELs and students with LD (NCES, 2018a; 2018b). Students with LD have poorer science test scores than students without LD. On the NAEP science test, students with LD scored lower on average (131 in fourth grade, 124 in eighth grade), with fewer students at or above the basic level (53% fourth grade, 34% eighth grade), than students without disabilities (157 fourth grade, 158 eighth grade; 79% at or above basic level in fourth grade, 72% in eighth grade) (NCES, 2018a; 2018b). ELs also perform more poorly in science on average (121 fourth grade, 110 eighth grade), with fewer students at or above basic level (41% fourth grade, 19% eighth grade) than English-proficient students (158 fourth grade, 157 eighth grade; 80% at or above basic level in fourth grade, 71% in eighth grade) (NCES, 2018a; 2018b). These results indicate a widening gap between students from elementary through middle school in science. ELs also experience lower graduation rates from high school (66.9%), as do students with LD (65.5%), compared to the overall U.S. graduation rate of 84.1% (NCES, 2016).
